PROBLEM TO BE SOLVED: To provide "a route search system and a computer system" for setting a route in which an automatically operable section and an automatically non-operable section do not coexist.SOLUTION: An express highway is registered in a level-3 hierarchy, an automatically operable road other than the express highway is registered in a level-2 hierarchy, and a road in an automatically non-operable section is registered in a level-1 hierarchy. A route search is performed by repeating a process to search for a route portion up to the junction of a road of one level higher hierarchy, each of a current position and a destination being a start point, until a route portion up to the level-3 hierarchy is searched, and then searching for a route portion at the level-3 hierarchy linking two route portions searched from the current position side and the destination side each, and connecting each of the searched route portions to find a route from the current position to the destination.SELECTED DRAWING: Figure 3
